Free graphs software for mac

Graph any explicit or implicit relation or inequality in rectangular or polar coordinates. Explicit graphing (y=, r=, etc) is instant, but implicit relations are graphed with brute force, and may take a few seconds.

Basically, this will graph ANY equation or inequality that contains an x, y, r, or t (theta). It does not have to be in a y= format.

Rtgraph is a collection of real-time graphing widgets for Gtk 2, written in Python. Rtgraph includes widgets for scrolling polar graphs, cartesian 3D graphs, line graphs, and UI elements for manipulating these graphs.
Tweak is a companion module included with rtgraph, for easily building Gtk user interfaces for manipulating data in real-time. Tweak makes it very easy to bind a set of python attributes in existing objects to a simple Gtk UI. It is used by some or rtgtaphs UI components, but is also quite usable on its own.
NOTE: Rtgraph is licensed and distributed under the terms of the GNU LGPL.

Main features:
- Scrolling line graphs
- Polar vector graphs
- 3D vector graphs using an isometric view
- All graphs support any number of channels, with automatic or manual coloring
- High level classes for quickly creating a user interface displaying a group of input signals

System requirements:
-
- PyGTK

AP Graphercan be used to graph the signal strength of a wireless base station such as Apples Airport Basestation.
Use it to help position your base station for optimal signal reception, or just for fun. It only shows the signal strength for a base station that you are currently connected to.
Enhancements:
- Fixed a number of possible issues with the size of the options drawer in different languages.
- Bug where drawer didnt always fully reveal itself should be fixed.

EdenGraph is a powerful graphing calculator, built for Mac OS X, which is able to plot two-dimensional graphs using standard algebraic or trigonometric functions.
Many mathematical packages only allow for static, rendered images of graphs, whereas EdenGraph lets the user dynamically shift, track, or magnify the current graph.
EdenGraph complements Mac OS Xs methodology: the power of UNIX with an elegant, easy-to-use, and intuitive user interface.
EdenGraph aims to provide simplicity and usability, while harnessing the power and legacy of UNIX.
EdenGraph wont break anyones pocketbook since it is available free of charge as freeware.
Main features:
- Plot simple functions in 2D space
- Zoom in and out
- Easily shift the graph by clicking on the screen and dragging or using the keyboard arrow keys
- Track where the mouse is positioned
- Save as TIFF, PDF, or EPS
- Copy graph image to clipboard
- Add, save, and edit your favorite equations
- Print graphs
- Change the color of the graph, background, axes, and grid
- Check for new updates
- Universal Binary
Enhancements:
- Now available as a Universal Binary for both Intel and PPC Macs.
- Several graphical and interface enhancements to the buttons and icons.
- Updated Help system.
- Minor problems fixed.

Graphing Functions 1.2 is a program for students to search and plot solutions to parabolas, hyperbolas, and absolute value functions applying an on-screen Cartesian plane and five moveable points.

The SM2DGraphView framework provides an NSView subclass which draws pie charts or graphs of lines and/or bars including axis labels. The SM2DGraphView class acts very much like an NSTableView or NSBrowser; SM2DGraphView takes responsibility for all of the drawing code but relies on a data source object to provide the specific lines and points to draw. A delegate object can also be assigned to a graph object to modify the behavior of the graph view.
The package includes Interface Builder (IB) palette to easily add graphs to your nib files.
Enhancements:
Enhancements:
- Added accessor to get the area of the graphpaper area (where the graph itself is drawn within all of the labels).
- Added accessors to get/set the title of the graph as an NSString or an NSAttributedString. Titles are drawn above the graph area.
- Non-ASCII graph symbols are now created as NSString from Unicode constants instead of cluttering up the InfoPlist.strings file.
- Changed the way bar graphs are drawn to use NSBezierPath and the CTGradient class.
- Added an override of the -print: method to make sure that SM2DGraphView and SMPieChartView objects are scaled down to fit on a single page if necessary. Added a "Print" button to the sample app to test this out.
- Non-ASCII graph symbols are now created as NSString from Unicode constants instead of cluttering up the InfoPlist.strings file.
- Changed the Xcode project configurations to have more options for what minimum OS version you are targeting. All of them build a Universal binary (except the Development target which builds only whatever youre compiling on).
Bug fixes:
- Fixed drawing the grid lines when the number of tick marks is 2 or more (instead of 1 or more).

Graphing Calculator is easy to use yet its features will amaze you. It is actually a free and open source scientific calculator for your Mac.
